1. Aerodynamics of vehicle platooning
Sammanfattning : Many factors are pushing automotive manufacturers to increase the efficiency of their fleets; some of these are legislative (requiring reduced greenhouse gas emissions) as well as ensuring sufficient range and power consumption in electric vehicles. An important part of improving the energy efficiency of road vehicles is reducing their aerodynamic drag. LÄS MER
2. Tyre aerodynamics of passenger vehicles
Sammanfattning : To decelerate climate change and limit global warming, there is a need for reducing the environmental impact of vehicles, which can be achieved by increasing their energy efficiency. For a passenger vehicle, one of the largest resistive forces is aerodynamic drag. LÄS MER
3. Subjective perception and prediction model of vehicle stability under aerodynamic excitations
Sammanfattning : The current automotive era is moving towards electrified vehicle propulsion. As a result, an energy efficient vehicle design becomes one of the top priorities. From an aerodynamics point of view, the vehicle should be more streamlined for minimal aerodynamic drag. LÄS MER
4. Sound propagation from sustainable ground vehicles : from aeroacoustic sources to urban noise
Sammanfattning : Transportation is the main source of environmental noise in Europe, with an estimated 125 million people affected by excessive noise levels from road traffic, causing a burden of noise related diseases and having a substantial economic impact on society. In order to reduce exposure to high levels of traffic noise, two approaches are the topic of extensive research: preventing sound from propagating from roads and railways using for example noise barriers, and reducing the sources of noise themselves.

5. Predictive model of perceived driving stability at high speeds under aerodynamic excitations
Sammanfattning : The automotive industry is continuously advancing towards more energy-efficient vehicle designs. Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when exposed to external excitations such as unsteady aerodynamic forces created by the flow of air around them.
